My rental units were not high-end houses like you will be looking for. I rented apartments and houses in the $600-2100/month range.
My favorite tenants were military people. I rented a Normal Hts house to a Navy seal and his wife and I rented apartments in IB and Pt Loma to any number of enlisted people.
I knew that these people were receiving a big chunk of money every month that was specifically for housing.
The housing allotment allowed them to pay rent and I felt like I had Uncle Sam covering my back if my military tenant caused any problems (hopefully not an issue when renting to officers).
Only once did I have to threaten to call an enlisted person’s chain of command and the threat accomplished my objective.
